Description

A wire cutting workbench bracket

technical field

The utility model relates to the technical field of electric spark wire cutting for special processing, in particular to a wire cutting workbench support.

Background technique

The wire cutting workbench bracket currently used in the workshop usually consists of two lateral support rods and two longitudinal support rods. The two lateral support rods are fixed on the workbench, and the two longitudinal support rods move on the two lateral support rods. Positioning, placing the workpiece on the longitudinal support rod, clamping the workpiece, and cutting, however, the worktable bracket of this structure still has the following shortcomings:

1. The clamping method of this bracket is to open 6 threaded holes equidistantly on the upper surface of the longitudinal support rod, use the screw to pass through the bolt and the pressure plate, and tighten with the threaded holes, and the pressure plate compresses the workpiece on the worktable, so as to cut , However, this method is not only limited by the distance of the threaded holes on the longitudinal support rod, it cannot continuously move the position where the pressure plate is pressed, and the use is not flexible enough, and every time it is pressed and loosened, a wrench is required to twist the bolt, which is troublesome and stressful. The effect is also unsatisfactory;

2. The horizontal support rod and the longitudinal support rod are pressed and fixed by screws and bolts. When the position of the longitudinal support rod needs to be moved, a wrench should be used to loosen the bolts. After moving in place, use the wrench again to twist the bolts. tight, the process is troublesome, and the position adjustment of the longitudinal support rod is too time-consuming;

3. The longitudinal support rod is not light in weight, and the whole is directly pressed on the horizontal support rod. There is no connection mechanism between the two. When moving the longitudinal support rod, it is often pushed manually, and the contact friction between the surfaces makes the It takes a lot of effort to push, which is time-consuming and labor-intensive, and the work efficiency is low;

4. The longitudinal support rod is a straight cuboid. When pressing the workpiece, it can only press a point on the edge of the workpiece. For some special workpiece cutting requirements, it cannot be directly met. It needs to constantly change the fixed point to complete the cutting, and the process is complicated and tedious;

5. The whole bracket does not have any support or protection for the dropped workpiece during the cutting process. When cutting large workpieces, the molybdenum wire is often cut at the end of the cutting due to the workpiece falling, and the parts under the worktable are smashed, which is a great safety hazard, or The downward displacement of the workpiece during the cutting process affects the machining accuracy, which is difficult to popularize and implement.
